Deuteronomy 30:2, 8, 20

and you return to the LORD your God and obey Him with all your heart and soul according to all that I command you today, you and your sons

And you shall again obey the LORD, and observe all His commandments which I command you today.

by loving the LORD your God, by obeying His voice, and by holding fast to Him; for this is your life and the length of your days, that you may live in the land which the LORD swore to your fathers, to Abraham, Isaac, and Jacob, to give them.”
